Cocaine (Configurable Omnipotent Custom Applications Integrated Network Engine) is an open-source PaaS system for creating cloud hosting for apps, much like Google App Engine or Heroku.

Any library or service can be implemented in Cocaine using a special API. Some of the most essential services are already provided in the form of plugins: Elasticsearch, URL Fetcher, tools for logging, and also access to data storage systems Elliptics and MongoDB.
